SUPPORT FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 675,358, dated May 28,1901.

Application filed December 22, 1900. Serial No. 40.820. (No model.)

To aZZ whom it may'concern:

Orchard street, San Jose, in the county of Santa Clara and State ofCalifornia, have invented certain new and useful Improvements inSupports for Bicycles; and I do hereby declare the following to beefull, clear, and exact description of said invention, such as willenable others skilled in the art to which it most nearly appertains tomake,use, and practice the same. I p I This invention relates toimprovements in bicycle-supports.

The object of the invention is .to provide suitable means carried-on thebicycle-frame for supporting thebicycle in a standing position and,further, to lock the same in standing position.

In the drawings, Figure 1 is a side elevation of the invention inoperative position, portions of the bicycle being shown in dottedconstruction. Fig. 2 is a similar view in inoperative position. Fig. 3is a front elevation of the mechanism for locking the front wheel. Fig.3 is a side elevation of the lock ing-hasp for securing the frontwheel'with a key-lock. Fig. 4 is a rear elevation of the supporting-legsand their immediate mechanisms in operative position. Fig. 5 is a planview of the lever mechanisms for throwing the parts into and out oftheir normal position. Fig. 6 is a side elevation of the same.

The invention consists of the front-wheellocking mechanism A, thespreading'supporting mechanisms B, and the actuating mechanisms O,intcrmediately located for operating and locking the mechanisms A and B.

In the description with reference to the drawings the minor mechanismsof the abovedesignated groups will be given the distinguishing commonletter strengthened by a numeral.

The locking mechanism A consists of ayoke member whose side pieces A Aare capable of a lateralspringiness, and this feature is best achievedby forming the yoke of two strips of sheet-steel. The upper ends,forming the stem A of the yoke, are brazed or otherwise secured togetherfrom the head of the stem to the offset A of the yoke. The

bar A is extended between the side pieces A A to bear against the treadof the' bicycletire, the perforations A in the side pieces permitting ofan adjustment to accommodate the various diameters of tires, &c. Thedepression of the bicycle-tire by the bar A and compression by the sidepieces A A Figs. 1 and 2, constitute an effective lock for the frontwheel of the bicycle. The head of the stem A is pivoted in the block A",held rigidly against the under side of the forward brace X of thebicycle-frame by the encircling clamp A The finger-spring A, the rigidend of which is secured between the block A and clamp A the free endbearin g against the pin A in inoperative position holds the look A inposition and prevents rattling of the parts. The concentric extension Aon the stem A is pivoted to the connecting-rod O, which connects withthe pivotal stud 0 into which its threaded end is screwed, permittingadjustment. The stud 0 is mounted on the end of the lever 0 pivoted onthe clamp O of the actuatingmechanism. To look the side pieces A A?together under the rim of the front wheelof the bicycle, the hasp-bar Ais hinged to the lower extremity of the side piece A the free end of thehasp A being provided with the catch A adapted to engage the bolt of asuitable look A, secured to the lower extremity of the side piece A. Thehasp A is so hinged as to allow for the lateral separation of the sidepieces A and A The hasp A extends under the rim of the wheel between thespokes, locking the wheel so that it can be released only by the holderof the key to the lock A The hasp A can be secured in inoperativeposition against the side piece A as shown in dotted lines, Fig. 3, bythe glove-button device A on the hasp, sprung into a perforation in theside piece A The supporting-legs B, pivoted behind the operating-leversO and C consist of the rods B,.telescoping within the tubes B which arepivoted between the plates B and B, the former being pivoted in a lug onthe clamp. B encircling, the tube X of the bicycleframe. tension B, towhich the connecting-rod C is attached, the rod connecting with thelever C in the manner described with reference to the rod 0 and lever 0The tubes 13 are spread laterally by a knuckle connection con- The plateB is provided with the ex- IOO sisting of the bars 13 and B their outerends being pivotal on the adjustable lugs 13 on the tubes 13 B the innerends of the bars B B being pivoted on a stud B into which theupwardly-extending rod 13 is screwed. The upper end of the rod 13 ispivoted to a block B adjustably secured to the under side of the tube Xof the bicycle-frame. Fulcrumed in a clamp 13 behind the clamp is thelever B, which is pivoted above the fulcrum to the connecting-rod C,which connects with the actuating-lever C in the manner described withreference to the rod 0' and lever C Below the fulcrum the lever 13reaches downward, a portion of its cX- tremity being bent at an angleand slotted to receive the rod 13.

The operation of thisinvention, supposing the parts to be in inoperativeposition, Fig. 2, is as follows:

First. Grasp the handle C on the lever C and throw to the left untilthelever 0 comes in contact with the lug or oifset 0 011 the similarlever C This action throws the locking mechanisms Adown, releasing theends of the supporting-rods B.

Second. Grasp thehandle C on the lever (J and throw to the left untilboth levers C and C are sprung under and locked in position by theextension C on the clamp C. This last action throws the lockingmechanism A into contact with the front wheel of the bicycle and thesupporting mechanisms or legs in contact with the ground, as shown inFig. 1.

The rod B, being pivotedbehind the pivotal center of the rods B 13*,causing an eccentric action, acting upon the knuckle constructioncomposed of the bars B B causes the extension and contraction of thesupporting-rods B B (See interrupted lines of action, Fig. l.)

The lever B, operated by the actuatinglever C through the connecting-rodG which lies above the fulcrum-pin (3 when the parts are in openoperative position, acts as rear brace for the supporting mechanisms B,relieving the actuating mechanism 0 from direct strain in the operativeposition and combining with the detent C to hold the parts locked insaid position. It is advantageous to adjust the supporting mechanisms sothat in the operative position one of the supportin g-rods B restsagainst the forward sprocket X of the bicycle-gear. The lever B and itsmechanisms may be dispensed with without seriously crippling the actionof the supporting mechanism.

The supports of the bicycle extending to either side of the center ofgravity throw the weight of the bicycle upon the wheels instead of uponthe supporting mechanism, which may be made materially lighter, &c., inconsequence.

The spread of the supporting-rods B may be regulated by sliding theblocks 13 B on the tubes B B or by advancing or receding the pivotalpoint of the rod 13, which may be accomplished by relieving the clamp 13and adjusting the block 13 The adjustment of the connecting-rods of theactuating mechanism 0 is accomplished by the threaded connectiondescribed with reference to the levers C C.

The pressure on the front tire by the bar A is regulated by theadjlisting-perforations A".

The mode of lengthening or shortening of the supporting-rods is obviousby the telescoping of the rods B and tubes 13.

As is apparent by the construction above described, this bicycle-supportis applicable to any of the accepted designs of safety-bicycles.
